IMPROVEMENT IN GATES.

Specification forming part of Letters Patent No. 116,202, dated June 20,1871.

To all whom it may concern:

Be it known that I, NATHAN LONG, of Muncie, in the county of Delawareand State of Indiana, have invented certain new and useful Improvementsin Self-Acting Gates; and I do hereby declare that thefollowing is afull, clear, and exact description thereof, reference being had to theaccompanying drawing and to the letters of reference marked thereonwhich form a part of this specification.

The nature of my invention consists in the construction and arrangementof a gate having no springs or similar devices, but opening and closingsimply by its own gravity, and not depending from hinges placed in avertical line, but from two points considerably removed from each other,as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my'inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, whichrepresents a perspective view of my gate.

A represents the frame, which is constructed of iron or Wood, puttogether in the form of a cross, and bolted together, then anchoredbelow the surface of the ground. B B are three braces, made of one-inchrod or cast iron, and bolted to the frame A, and connected at the top bythe spider J. E is an upright rod resting or moving on an incline, P,guided by the slot 0 in the same, said slot being at an angle with thegate R. The incline P gives the gate an upright and the slot 0 ahorizontal motion. The upright rod E passes through an eye in the spiderJ, and the gate R is connected to said rod at the upper end by aninverted cup, S, upon which it rotates, and near the lower end by theforked bar or guide Y. Upon the incline P is a catch, 0, to prevent thegate from being lifted off from the upright rod when closed; and an arm,T, extending from the rod E, prevents the rod from turning on theincline. The gate R is an ordinary farm-gate, and provided on the lowerrail with a toothed bar, F, to prevent hogs from rooting under orrubbing against the gate.

It is eperated by the following means: A horizontal rod, N, is connectedto the upright rod E in the center by the pitman Z, and at each end by asimilar pitman, with a double right-angle crank, M, constructed so thatwhen one or the other of these cranks is upright the other ishorizontal. The elevation or depression of one or the other of thesecranks moves the upright rod E on the incline, and throws the gate at anangle from the direction it will swing. This change of position changesthe center of gravity, and the gate will swing swiftly to place, Whereit is held by latches K K. These latches are so constructed that theywill take up the jar of the gate as it swings open or closes.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. The incline P with slot 0 and catch 0, substantially as and for thepurposes herein set forth.

2. The combination of the gate R, inverted cup S, arm Y, and rod E, saidrod placed in the slot 0 on the incline P, and in an eye on the spiderJ, substantially as and for the purposes herein set forth.

3. I11 combination with the incline P and catch 0, the rod N, pitman ZZ, and double crank M, all arranged to operate substantially asdescribed.

In testimony that I claim the foregoing as my own I afix my signature inpresence of two witnesses.
